CLEAN WATER AND SANITATION
Ensure access to water and sanitation for all
Over 844 million people in the world live without access to a basic drinking water service, and 2.3 billionhave no access to a basic sanitation service, resulting in avoidable deaths, chronic disease, fewer hours of education and low productivity.
ACCIONA has positioned itself as a key player in the water treatment sector. Its innovative management seeks to resolve the challenges with respect to the shortage of water resources.
Take urgent action to combat climate change and its impacts
The generation and use of energy accounts for 74 % of total greenhouse gas emissions in the world. This activity is the largest contributor to global warming. Investment in renewable energy, energy efficiency and other low-carbon technologies will continue to be essential to meet the emerging needs of humanity and to minimize their negative impact on the environment.
ACCIONA considers the fight against climate change and its effects to be a strategic priority. The company works to mitigate greenhouse gas emissions in order to contribute to the progress of society and respond to the main challenges of sustainable development in the areas of infrastructure, water and energy, leading the transition to a low-carbon economy.
The town of Toro is located on a hill at whose feet the river Duero flows. The heart of an eminently cattle raising and farming area, it is expanding heavily in the wine producing sector. New sources for the town’s economic development are growing tourism and the renewable energy industry.
ACCIONA has been running the Toro service since 2001, both as to supply and sewerage and water treatment via a 25 year concession.The work centre currently employs 10 workers who ensure that the Service works correctly, with the different functions each has, amongst which are subscriber management, meter reading, water quality control, repairing faults, building new systems and connections, maintaining catchments and the W.W.T.S., etc.
The supply infrastructure that ACCIONA runs consists of modern catchment facilities in the Eras de Santa Catalina district, altered and improved in the last year by ACCIONA through being awarded thereto.
The supply pipes are fairly old although they are currently being renewed for new, more suitable cast iron pipes in view of the town’s peculiarity, the wine cellars that were dug out by our ancestors for making the district’s renowned wines.
Another town in the province of Zamora, Corrales, is also managed from Toro.
